Google Sheets: How to Write a Custom Function

Google Sheets (spreadsheets) lets you write custom functions using JavaScript.  JavaScript is perhaps the world’s easiest programming language, and there are many examples on the internet, making it easy to copy. There are lots of reasons to write your own functions.  For example, you could convert a temperature reading from Celsius to Fahrenheit. You could make a cell change color if your budget shows a shortage.  You could program the commission you pay your employees based on the formula you use.  Some of these things you can do with the functions that are already in Google Sheets.  However, if you write your own function, then people who share documents with you can reference those and not have to recreate that logic. Here’s how to write a custom function in a Google Spreadsheet.

Google Slides is a good alternative to Power Point, and it is much easier to use than Visio. You can use Google Slides to make eye-popping presentations or just draw simple charts and diagrams.

Google has come under much criticism for using your personal data for advertising and tracking.  In a gesture addressed toward their many critics, Google has added a private browsing feature to Chrome called incognito mode that can help you opt out of tracking. It works, but only for a very short duration.  Web pages can still track you when you use it.  However, since it erases cookies when you close the Incognito Mode window, advertisers and data brokers cannot track you long enough to target advertising to you or sell your data to data brokers.  

With incognito mode, Google states: “You don’t leave browsing history and cookies on your computer, but you can still see your existing history, bookmarks, passwords, Autofill data, and other Chrome settings.”
